"Labor Day is summer’s last hurrah, and families from across the country will be flocking to the beach this weekend to soak in some final rays. Beachgoers on the East Coast making their way to Cape Cod or one of six other National Seashores, however, might want to pause and take an extra look around at the wind-tossed dunes and sloping sands. Not just because summer is coming to an end, but because these areas are some of the most susceptible to the effects of climate change and may look very different, very soon."
